Which question pertains to case history and asks about lesions, irregular growth, or fungal signs?

• A. When did this occur
• B. Grass type
• C. Are there lesions on leaves, irregular growth, or fungal signs?
• D. Irrigation regimen

Answer: (C)

The main idea is using case history questions that capture what symptoms are visible on the plant. Lesions on leaves, irregular growth, or signs of fungi are concrete clues you can observe directly, and they point to what kind of problem you’re dealing with—disease or a pest issue. This question is the one that directly asks about those symptoms, giving you the essential information to form a diagnosis. The other prompts focus on when the issue started, the type of grass, or the irrigation routine—useful for context but not about the actual plant symptoms you’d rely on to identify the problem. So, asking about lesions, irregular growth, or fungal signs is the most informative for a case history.
